    • an over-all name for reputation for the measures in which any living system features acquired the morphological and physiological characters which distinguish it; a gradual unfolding of successive phases of development or development.
    • That theory of generation which supposes the germ to preëxist in the parent, and its parts to be developed, but not actually formed, by the procreative act; -- opposed to epigenesis.
    • That number of modifications under normal legislation that involves constant progress from the homogeneous to the heterogeneous in construction, and from solitary and easy towards different and manifold in quality or function. The process is by some limited to natural beings; by others it is placed on the inorganic therefore the psychical. Additionally, it is placed on explain the existence and growth of organizations, ways, language, society, and each product of real human task. The agencies and legislation of this process are variously explained by various philosophrs.
    • The act or procedure of unfolding, and/or state of being unfolded; an opening out or unrolling.
    • Hence The process of evolving or becoming developed; an unfolding or development from, or as though from, a germ or latent condition, or from an idea; development: as, the evolution of record or of a dramatic story.
    • particularly— In biology: the particular formation of a part or of whole of an organism which formerly existed just as a germ or rudiment; ordinary normal growth, at the time of living animals, from the germinal or embryonic to your adult or perfect state: because, the development of an animal through the ovum, or of a plant from seed; the development of the blossom through the bud, or of fresh fruit from the flower; the advancement of the butterfly from the caterpillar; the advancement regarding the mind from primitive cerebral vesicles, or associated with the lung area from an offshoot associated with intestine.
    • the production, emergence, or exclusion of an animal or a plant, or of some phase or part thereof, from any covering which contained it: as, the development of spores from an encysted animalcule; the advancement of a moth from cocoon, of an insect through the wood or dirt by which it existed as a larva, of a chick from the egg-shell which included it as an embryo.
    • lineage or derivation, as of offspring from moms and dads; the result of generation or procreation. As an undeniable fact, this evolution isn't ready to accept concern. As a doctrine or theory of generation, it really is vulnerable of different interpretations. In a single view, the germ actually preëxists in one single and/or various other parent, and it is simply unfolded or expanded, but not really created, within the act of procreation. (See ovulist, spermatist.) This view is generally abandoned, current viewpoint becoming that all mother or father furnishes materials for or perhaps the substance of germ, whose evolution benefits from union of these elements. See epigenesis.
    • the very fact or even the doctrine of this derivation or lineage, with adjustment, of current species, genera, orders, courses, etc., of animals and plants, from a couple of easy forms of life, if you don't from a single; the doctrine of derivation; evolutionism. (See Darwinism.) Inside good sense, development is against creationism, or perhaps the view that every residing things happen produced sometime significantly as they now exist. Modern evolutionary concepts, but tend to be less worried about the problem for the origination of life than with concerns regarding the methods wherein residing organisms have actually assumed their actual figures or types. Phylogenetic advancement insists upon the direct derivation of all kinds of life off their antecedent kinds, in simply no other way than as, in ontogeny, offspring are derived from moms and dads, and consequently grades all actual affinities based on propinquity or remoteness of genetic succession. It presumes that, generally, these types of derivation or lineage, with modification, is from more standard toward more complicated types, from reduced to high in business, and from the even more general into the more specialized in structure and function; but inaddition it recognizes retrograde development, degeneration or degradation. The doctrine has become accepted by most biologists as a conception which many almost coincides with all the ascertained facts in the case, and which well explains observed realities, though it is held with several tones of specific viewpoint in this or that particular. See natural choice, under choice.
    • as a whole, the passageway from unorganized efficiency to orderly complexity (which, to a nicer and more sophisticated arrangement for reaching definite ends), this procedure being considered to be of the nature of an improvement. Therefore, the development of planetary figures from nebular or gaseous matter, plus the reputation for the introduction of someone plant or pet, or of society, are types of advancement.
    • Continuous succession; serial development.
    • In mathematics: In geometry, the unfolding or orifice of a curve, and rendering it describe an evolvent.
    • The removal of origins from abilities: the opposite of involution (which see).
    • A turning or moving activity; a passing back-and-forth; modification and interchange of place, especially for the working-out of a purpose or an agenda; especially, the action of soldiers or boats of war in wheeling, countermarching, manœuvering, etc., for disposition so as of fight or in range on parade: generally speaking when you look at the plural, to state the complete series of movements.
    • what is developed; something; an outgrowth.
    • In ancestral development or phylogeny, the doctrine or opinion your specific constitution or design which a germ-cell is held to own at the start of its development, also to which the business of the being that's produced from this is attributed, preexisted in germ-cells of preceding generations. Inside extreme kind in which it was held because of the embryologists for the seventeenth and eighteenth centuries it will be the doctrine that since individual development is and constantly is the unfolding of preexisting construction, each successive organism has actually existed, therefore, right from the start, when you look at the germ-cells of the very first ancestor, and in those of consecutive ancestors, such that it is not the real modem system, but just its visibility or perceptibility by feeling that's brand-new. The customizations for this doctrine by newer embryologists, with wanted making it in line with the progress of biological science, are too subtile and refined for concise declaration.
    • In biology, the doctrine or viewpoint, accepted as an existing truth by all recent biologists, that every living beings came into existence, in span of nature, by continuous descent, without break of continuity, from a couple of old and easy forms of life, or from a single.
    • an ongoing process which one thing passes by levels to another stage (especially a far more higher level or mature phase)
    • (biology) the sequence of activities involved in the evolutionary growth of a species or taxonomic set of organisms
    • A gradual procedure for which one thing changes into another and in most cases more complex or much better form. See Synonyms at development.
    • The process of building.
    • Gradual development.
    • Biology Change in the hereditary composition of a population during consecutive generations, due to natural choice functioning on the hereditary variation among people, and resulting in the introduction of new types.
    • Biology The historic development of a related number of organisms; phylogeny.
    • A movement that is element of a set of purchased movements.
    • Mathematics The removal of a root of a quantity.
    • gradual directional modification particularly one causing an even more advanced level or complex kind; development; development
    • The change in the hereditary composition of a population over successive years.
    • The removal of a root from a quantity.
    • among some bought motions.
    • A turning motion regarding the human body.
    • The act of unfolding or unrolling; therefore, any procedure for development or development.

    • A prescribed movement of a body of troops, or a vessel or fleet; any action built to impact a brand new arrangement or disposition; a maneuver.
    • A general name when it comes to reputation for the measures through which any living system features acquired the morphological and physiological characters which distinguish it; a gradual unfolding of consecutive phases of development or development.
    • That concept of generation which supposes the germ to preëxist in the moms and dad, as well as its components to be created, yet not actually created, by the procreative act; -- against epigenesis.
    • That a number of modifications under natural legislation that involves constant development from the homogeneous into the heterogeneous in structure, and from the solitary and easy to the different and manifold in quality or purpose. The procedure is by some restricted to natural beings; by other individuals it's put on the inorganic therefore the psychical. Additionally, it is put on explain the presence and growth of institutions, ways, language, society, and every product of person task. The agencies and rules associated with the procedure are variously explained by different philosophrs.
    • The work or procedure of unfolding, or perhaps the state to be unfolded; an opening out or unrolling.
    • therefore The process of developing or becoming developed; an unfolding or growth from, or like from, a germ or latent state, or from a strategy; development: as, the advancement of record or of a dramatic land.
    • especially— In biology: the particular formation of part or of the whole of an organism which previously existed only as a germ or rudiment; ordinary all-natural growth, at the time of living animals, through the germinal or embryonic into the person or perfect state: since, the advancement of an animal from ovum, or of a plant from the seed; the evolution associated with bloom through the bud, or for the fruit through the rose; the evolution associated with the butterfly through the caterpillar; the development associated with mind from primitive cerebral vesicles, or of lung area from an offshoot regarding the intestine.
    • the production, emergence, or exclusion of an animal or a plant, or of some stage or component thereof, from any covering which included it: as, the evolution of spores from an encysted animalcule; the development of a moth from cocoon, of an insect from lumber or mud where it lived as a larva, of a chick from egg-shell which included it as an embryo.
    • lineage or derivation, since offspring from parents; the actual results of generation or procreation. As an undeniable fact, this development isn't ready to accept question. As a doctrine or theory of generation, it's vulnerable of various interpretations. In one view, the germ in fact preëxists in one single or perhaps the various other parent, and it is merely unfolded or broadened, not actually formed, when you look at the work of procreation. (See ovulist, spermatist.) This view has become usually abandoned, the existing viewpoint becoming that all mother or father furnishes materials for and/or substance of germ, whoever development results from union of these elements. See epigenesis.
    • the actual fact or even the doctrine of this derivation or descent, with modification, of most existing species, genera, instructions, classes, etc., of creatures and flowers, from some quick kinds of life, or even from a single; the doctrine of derivation; evolutionism. (See Darwinism.) Within feeling, development is against creationism, and/or view that every living things have-been developed at some time significantly while they now exist. Modern-day evolutionary theories, but tend to be less worried about the issue of the origination of life than with questions regarding the ways and means where living organisms have presumed their particular actual characters or types. Phylogenetic advancement insists upon the direct derivation of forms of life off their antecedent forms, in simply no other way than since, in ontogeny, offspring derive from moms and dads, and consequently grades all actual affinities based on propinquity or remoteness of hereditary succession. It presumes that, as a rule, these types of derivation or descent, with customization, is through the more simple towards the more complex forms, from reduced to high in company, and through the even more generalized toward even more specialized in construction and function; but it addittionally recognizes retrograde development, deterioration or degradation. The doctrine has become acknowledged by most biologists as a conception which many almost coincides using the ascertained details in case, and which best describes seen details, though it really is held with many colors of individual opinion in this or that one. See all-natural choice, under choice.
    • as a whole, the passage from unorganized user friendliness to organized complexity (this is certainly, to a nicer and much more elaborate arrangement for reaching definite ends), this technique becoming thought to be of the nature of an improvement. Hence, the development of planetary bodies from nebular or gaseous matter, therefore the history of the introduction of someone plant or animal, or of culture, tend to be types of development.
    • Continuous succession; serial development.
    • In math: In geometry, the unfolding or opening of a curve, and making it explain an evolvent.
    • The extraction of origins from abilities: the reverse of involution (which see).
    • A turning or shifting activity; a passing backwards and forwards; change and interchange of position, particularly for the training of a purpose or a plan; especially, the activity of troops or vessels of war in wheeling, countermarching, manœuvering, etc., for personality in an effort of battle or in line on parade: generally inside plural, to convey the entire series of movements.
    • That which is evolved; an item; an outgrowth.
    • In ancestral development or phylogeny, the doctrine or viewpoint that certain constitution or architecture which a germ-cell is held to obtain at the start of its development, and that the organization associated with the becoming that is generated from this is attributed, preexisted inside germ-cells of preceding generations. In severe kind by which it had been held because of the embryologists of the seventeenth and eighteenth hundreds of years it is the doctrine that since individual development is and constantly has-been the unfolding of preexisting framework, each successive organism features existed, as a result, from the beginning, in the germ-cells of their very first ancestor, and in those of most successive forefathers, so that it is not the real modem system, but only its visibility or perceptibility by sense that's new. The improvements with this doctrine by more modern embryologists, who've looked for to really make it consistent with the development of biological technology, are way too subtile and processed for concise statement.
    • In biology, the doctrine or opinion, accepted as an established truth by all present biologists, that most living beings attended into presence, in length of nature, by continuous descent, without break of continuity, from several old and simple types of life, or from one.
    • an ongoing process by which one thing passes by levels to a different phase (especially an even more higher level or mature phase)
    • (biology) the sequence of activities involved in the evolutionary growth of a species or taxonomic set of organisms
